Potassium sulfate is chemically neutral, physical acidic fertilizer
Potassium sulfate is chemically neutral, physical acidic fertilizer, widely applicable to all types of soil and various crops, in particular, avoid chloride, potassium chloride potassium replacement, a good potash. Their specific use are:
(1) can be used as base fertilizer. When using potassium sulfate as basal dry, deep application must cover soil to reduce the potassium crystal fixed, and beneficial to crop root absorption and improve efficiency. (2) used as fertilizer. As the mobility of potassium in the soil less, should focus on the application or pit to be more dense root layer to enhance absorption. (3) can be used as types of fertilizer and foliar application. Acres planted in fertilizer consumption of 1.5 to 2.5 kilograms, can be made into 2% to 3% solution for foliar application. Use of potassium should be aware of the following three main issues: (1) for the reduction of paddy fields a strong soil, less potassium chloride, the main drawback is easy to produce hydrogen sulfide poisoning. (2) potassium sulfate prices are more expensive, in general, in addition to avoid chlorine plant, the Can not use potassium chloride to potassium sulfate. (3) of the cruciferous crops, more crops need sulfur, is better, priority should be assigned to use.
